Balance Shaft Bearing Installation

Tools Required

J 44225 Balance Shaft Bearing Remover/Installer





Position the cylinder block so the cylinder head deck face is down and identify the following:

* The left balance shaft bearings are in the shorter length balance shaft journal (3) and (4).
* The right balance shaft - grooved bearings are in the longer length balance shaft journal (1) and (2).





Identify the following:

* Bearings (2) and (3) are the front bearings and bearings (1) and (4) are the rear bearings.
* The rear bearings (1) and (4) have a slightly larger diameter than the front bearings (2) and (3). This allows for easier removal and installation of the front bearings. The rear bushings also have notches on them for identification purposes.
